' MORGAN A DEIa'BEIREI. GREENE, QF RUPEBQIDAHO HOSE-COUPLING.

Be; itknown that I, MoRenN a cit zen of the United States, and a residentof Itupert in .the county of Minido'ka and Stateof Idaho, have invented certain new and useful Improvements in Hose- Couplings, of which the following is a specification.

My invention relates to the hose couplings for use in-air" or steam systems of railway trains, between cars, and the main object thereof is to provide means for automatically coupling the sections together when two cars are coupled and for automatically uncoupling the same when the cars are uncoupled.

My invention is fully described in the following specification, of which the accompanying drawings form a part, in which like characters refer to like parts in each of the views, and in which Figurel 1s=a plan vlew 'of two compleme'ntal hose or; pipe coupling members, as on'adjoiningcar ends, uncoupled;

F'g ..2 is a similar view thereof, coupled; Fig. 3 is a side elevation of one member, showlng its position with respect to the car coupler;

. Fig. l is a section taken on the line 44 of Fig. 3; a Fig 5 is a section taken on the line 55 ofFig. 1; i

Fig; 6 is a sectional view of the hose or pipe heads coupled; and w I :Fig. 7 is aview similar "to Fig. 2 but showing a modification thereover. y

Referring to the drawings, 8 represents I the; head.v and "'9 the draw-bar of a car couplei' of anydesired form beneath which my invention is suspended, in single ,or multiple form, by means of links 10'and 11 in such manneras to swing longitudinally of the car, said links carrying a frame 12 in which i a pipe 13 is slidably mounted though normally held with a flange 14: thereon against a crossbar 15 of the'frame by means of a spring 16 hearing against a cross-bar 17'of said frame, and

in forward POSllBlJn by means of a spring ,18 interposed between said cross-bar 17 and a bifurcated bracket. 19 secured in any desired manner to the draw-bar 9, a crossbar 20 limiting forward frame movement.

The pipe 13 isconnected with the stationary piping 21- beneath the car by means ofajmseseetion is prevented against Specification of Letters Patent.

rotary movement by making the same: angular or, asillustrated, by the provision ofears '23 slidably mounted in corresponding grooves 24 in the cross-bar 15, Fig. 4.

Each frame 12 'is provided with a forwardly directed finger 25 on one side and with an angularly arranged guide 26 at its other side whereby, when the two frames are forced into operative connection, the

finger 'of one frame will be guided against the side of the other frame by the guide 26 on the latter, thus alining thetwo frames and preventing relative lateral. motion therebetween. v i

Each frame is furtherprovided with an inclined guideway- 27 shown as pivoted, for

sengercoaches but I do not desire to l1mit myself to either single or multiple type.

Each pipe 13 is' provided with ahead 29 I having a bore 30 therethrough the end'of which is inclined as shown at 31, Fig. 6,'and.

preferably suitably packed as by gaskets 32 or in any other desired manner, the outer end of each head being provided with an inclined tongue 33, a reversely inclinedsurface 34:, and a groove 35 arranged parallel *t0 the tongue 33, Figs. 1, 2, 6 and 7-, the

tongue of one head being adapted to enter the groove in the other head to form a lock,

- the surfaces 34: hearing one upon the other.

When'separated, the-tongues 33 are in the approximate line of the respective sides of the opposite heads though extending inwardly slightl so as to impinge on the inclin'ed outer si e of the complementaljgroove 35 when the heads are brought *togthei" whereby, as the heads continue to 'm'ove td ward each other, the respective tongues 33 will slide over the inclined sides of the re' spective g'rooves35 to cause the former, to be seated in the-latter, Fig. 6, this being in--- sured also by means of a-lug 36 on each head sliding over the inclined guideway 27 of the other frame 12, Fig. 2, :whereby a leakproof connection is formed between the heads when the cars are coupled together.

The heads 29 are, aswill be obvious, capable of a degree of lateral movement in order to'permit this engagement of the same but relative lateral movement is possible claims.

when the connection. is once made and, as will be understood, the-pipes 13 yield in a spring'resisted manner to compensate for relative axial movement of the car couplers, as do also the frames 12.

When tWo cars are uncoupled or drawn apart this hose or pipe connection is broken by reversing the above described operation ofjoining the heads 29 and the parts resume their nor-incl positions ready for another coupling operation The air or steam system may be controlled on each car b from either side of the car by rods 38 and I may provide a separate valve 37 for use in connecting a car provided with my hose coupler with one not so provided.

It will thus be seen that I provide two air or steam line heads on adjacent cars adapted to automatically enge in a leulcprocf man ner and to automatically separate when. the cars are uncoupled, no attention. on the part of the trainmcn being required other than operating the valve from the side of the car, thus obviating the necessity for goin be tween the cars and avoiding the acci ents, now common, due to this necessity.

The form shown in Fig. 7 is essentially the same asthat already described except that l substitute guides 39 for the guideways 27 and spring resisted bars 40 for the lugs 36, the operation being precimly as already described, and I may make other changes'in andmodifications of the forms shown and described, providingthat such changes do not departfrom the spirit of the invention andcome Within the scope of the appended Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In :1 hose coupling of the character specified, a longitudinally movable frame, a-

heald mounted on the frame and having an from ,independent longitudinal and lateral movement, and. coacting means between the head and frame for moving the head laterally in a positive and yieldable manner.

In a hose coupling of the character specified, a draw bar, a frame suspended the draw bar, a bracket carried by the draw bar, a spring between the bracket and frame normally pressing the latter forward,

a head mounted on the frame and having a limited longitudinal and lateral movement, a spring between the frame and head normeans of a valve 37'operablc Y mally pressing the head, forward, and COaCl'r ing members between the frame to yieldably press the head laterally.

3. In a hose coupling of the character described, frames, heads carried by the frames and having interlocking engagement, and cooperating means on the frames and heads for mcvmg said heads with respect to the frames.

- 4. Tn a hose coupling of the character described, mov'able frames having means for guiding them into engagement with one another, heads carried by the frame and ha"- ing interlocking engagement, and cooperating means on the frames and heads for moving said heads with respect to the frames.

7. In a hose coupling of the characterspecified, a frame, a head mounted on the frame to receive both a longitudinal and a lateral movement, an inclined guideway yieldably mounted. on the frame and a complemental' member carried by the head and acting jointly with the said guideway to yieldably press the head laterally.

8. In a hose coupling of the character specified, a frame, hose pipe sections mounted on the frame, each having a longitudinal and a lateral movement, and inclined guideways and coiiperating members between the frame and hose pipe sections for moving the latter laterally.
